WebALD is a superior method for thin film deposition which is used for fabrication of highly uniform and conformal Ir films over large and complex substrate areas. ALD is considered to be a special modification of CVD in which the substrate is exposed to one precursor at a time, the precursor pulses being separated by inert gas purging ( 95 ). Webiridium (Ir), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table. It is very dense and rare and is used in platinum alloys. A …

Atomic Layer Deposition of Iridium Thin Films

WebJun 17, 2024 · Here, heterogenized iridium complexes as photoredox catalysts were assembled via covalent attachment to metal oxide surfaces (ITO, ZrO 2, Al 2 O 3) in thin film or nanopowder constructs. The goal was to understand which materials provided the most promising constructs for catalysis. WebWith the present residual-water-molecule removal process, water molecules remaining in the system can be removed efficiently in the production of metallic thin films by the ALD method or the like, and thus, the film-formation time can be shortened and metallic thin films can be produced efficiently. 权利要求: 1. how to replace amd processor
